ccTLD

A ccTLD (country code Top Level Domain) is a domain extension tied to a country or territory – like .uk for the United Kingdom or .au for Australia. These domain extensions tell users and search engines which geographic market you’re targeting. When search engines see a ccTLD, they’re more likely to show your website in that country’s search results, making it easier for local users to find your business.
